Cull. All the species of this genus are elegant, delicate little 

 plants. The seeds should be sown in small pots, well drained 

 with sherds, in a mixture of gravel and peat, or sand, loam, and 

 peat ; and those species, natives of the sea-shore, may be wa- 

 tered occasionally with salted water.
